Style
His early works are written in an orthodox Soviet idiom. In the 1960s Shchedrin began incorporating different styles of music, such as Neoclassicism, pop music and jazz; in the 1970s he found his personal synthesis. Shchedrin defines his position as "post-avant-garde".
David Fanning wrote an essay on Shchedrin and his Symphony No. 2.
The composer himself wrote a counterstatement on several incorrect details and misinterpreations in Fanning‘s essay.
